Why are katydids so loud?
Katydids make sound by rubbing their forewings together. Cicadas have sound organs called tymbals, which have a series of ribs that can buckle onto one another when the cicada flexes its muscles. The buckling creates a clicking noise, and the combined effect of these clicks is the buzzing sound cicadas make.
